Inputs and outputs

A subsystem component has a set of sources and targets that are based on the sources and targets of the various maps that it contains. The sources and targets (inputs and outputs) are the interface points of the subsystem component used within a system.

In general, a system input is a component input that is not internally produced and a system output is a component output that is not deleted. When a system is presented as a component of another system, the subsystem inputs and outputs serve as interface points, allowing it to be connected to other components in the view.

Double-clicking a subsystem icon expands the view to show inputs and outputs. Double-clicking an input or output card displays the execution settings for the subsystem component.
